Grgina applicationiled November 17, 1910, Serial No. 592,899. Divided and this application ld Gctober 5, 1911. Serial No. 653,037.

To all 'whom it may concern:

Be it known that I, GEORGE WASHINGTON SLATER, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Driving Mechanism, of which the following is a specification.

This invent-ion relates to motor vehicles and the principal object of the same is to provide simple and efiicient driving means therefor which will apply the power 'equally to the frontand rear axle.

Another object ofl this invention is the production of a simple and eiiicient casting or casing acting as a shield for the driving gears.

This application is a divisional application, the original application of which was :tiled by -me on November 17, 1910, Serial No. 592,899.

Other objects and advantages of this invention will appear' in the following specification and claims.

In the drawings, Figure 1 is a view in side elevation of the motor truck. Fig. 2 is a vertical section taken through the center of the gear casing. Fig. 3 is a top plan view partly in section of the structure shown in Fig. 2.

Referrin to the accompanying drawings by numera s, it will be seen that the improved motor vehicle comprises a body 1 which is supported by the side bars 2, bein connected to the transversely arranged a e frames by means of springs 3.' An

engine 4 is carried by the body 1 and carries a drive shaft 5 which is provided with a universal joint 6 connecting the shaft 5L -With the drive shaft 7. The drive shaft extends into a gear housing 8 which is carried bythe rear axle of the vehicle and operates the usual gearing (not shown) for driving the rear axle. The drive shaft 7 also passes through a shield housing 9 which housing is\ supported by brackets 10 projecting 'from' the rear axle.- Within the housing 9 the shaft 5 carries a gear 11 which gear meshes l one of said sections of said housin gear thereon, said gear fitting in sai socket with a gear 12 carried by an auxiliary shaft 13 which shaft is also journaled in the 50 housing 9. The forward end of the shaft 13r projects beyond the housing 9 and carries a knuckle connection 14 with a drive shaft 15. This drive shaft 15 extends into a gear housing 16 carried by the front axle and 55 operates the usual gearing (not shown) for driving said front axle. v

The described arrangement of shafts ob-f viously applies the power equally to the front and rear axles, and the universal joint connection, permit the necessary relative movements of said shafts to compensate forshocksv and jars and the change of position incidental to the turns made by the vehicle.

As will be seen, by giving the drawing 65 careful consideration,` the shield housing 9 comprises an upper and lower-section substantially U-shaped at its rear end for allowing the same to straddle the gear housing therebyv constituting legs 17. Each ofthe sections is provided with a socket 18 into lwhich fits the gears 11 and 12 and these sections are brought together and securely held in their proper position by means of bolts passing through apertures 19.

1. A shield housing to be used in connection with a motor vehicle, comprising a pair of sections, each section being provided with a pair of legs adapted to straddle the axle of a vehicle for supporting said sectionsin engagement with the axle, each .of said sections being provided witha socket portion, `a drive shaft passingthrough vand a formed in one of saidv sections, an auxiliary shaft passing through the other of said sections of said housing and a gear thereon tting in said socket and meshing with saidr l first-mentioned gear, and means for securing said sections together. l

2. A device of the class described' comprising a main drive shaft, an auxiliary drive shaft, a sectional housing, a gear car'- 95 ried by each shaft and meshing with each Q romane other, said housing being provided With In testimony whereof I ax my signature sockets for receiving said gears and having in'presence of two Witnesses.
